Overview of this book

The Yocto Project is the industry standard for developing dependable embedded Linux projects. It stands out from other frameworks by offering time-efficient development with enhanced reliability and robustness. With Embedded Linux Development Using Yocto Project, you’ll acquire an understanding of Yocto Project tools, helping you perform different Linux-based tasks. You’ll gain a deep understanding of Poky and BitBake, explore practical use cases for building a Linux subsystem project, employ Yocto Project tools available for embedded Linux, and uncover the secrets of SDK, recipe tool, and others. This new edition is aligned with the latest long-term support release of the aforementioned technologies and introduces two new chapters, covering optimal emulation in QEMU for faster product development and best practices. By the end of this book, you’ll be well-equipped to generate and run an image for real hardware boards. You’ll gain hands-on experience in building efficient Linux systems using the Yocto Project.

Debugging packaging

In more sophisticated recipes, we split the installed contents into several sub-packages. The sub-packages can be optional features, modules, or any other set of files that is optional to install.

To inspect how the recipe’s content has been split, we can use the build/tmp/work/<arch>/<recipe name>/<software version>/packages-split directory. It contains a sub-directory for every sub-package and has its contents in the sub-tree.

Among the possible reasons for a mistaken content split, we have defined the following:

  • The contents not being installed (for example, an error in installation scripts)
  • An application or library configuration error (for example, a disabled feature)
  • Metadata errors (for example, the wrong package order)

Another common issue for build failure is lacking the required artifacts in the sysroot directory (for example, headers or dynamic libraries). The counterpart of the sysroot generation...
